FIG. 1A is a diagram illustrating a system that performs a function for providing a response message with respect to an incoming call, according to an exemplary embodiment.

Referring to FIG. 1A, a response message providing system includes first and second devices 100 and 200, in which the first and second devices 100 and 200 are electronic devices supporting at least a voice call function or a video call function. For example, the first and second devices 100 and 200 may be smart phones, tablet PCs, PCs, smart TVs, mobile phones, personal digital assistants (PDAs), laptop PCs, media players, micro servers, global positioning system (GPS) devices, e-book terminals, digital broadcasting terminals, navigation devices, kiosks, MP3 players, digital camera, and other mobile or non-mobile computing devices, but are not limited thereto. Furthermore, the first and second devices 100 and 200 may include various devices capable of receiving touch inputs, including, e.g., electronic blackboards and touch tables.

According to an exemplary embodiment, the first device 100 may be a device that executes software and performs particular functions via the software. Software may be executed by one from among an application, an operating system (OS), and a middleware, or any combination thereof. Particularly, a function of generating a response message according to an exemplary embodiment may be performed by one from among an application, an OS, and a middleware. Hereinafter, an embodiment in which the function is executed by an application and an embodiment in which the function is executed by a middleware will be described in detail. Furthermore, software may be executed not only by the first device 100, but also by other devices connected to the first device 100, e.g., a wearable device, a server, a navigation device, etc.

The term “application” may refer to a set of a series of computer programs designed to perform a particular task. The disclosure may include various applications. For example, applications may include a web browser, a camera application, a dictionary application, a translator application, a data transmission application, a music player application, a movie player application, a phone application, a message application, a social communicator application, a map application, a picture folder application, a broadcasting application, a game application, a fitness application, a payment application, a memo application, a calendar application, and a phone book application, but are not limited thereto.

“Middleware” may include a plurality of modules that are prepared in advance to provide functions that are commonly demanded by various applications. Middleware may provide functions via application program interfaces (APIs), such that applications may efficiently utilize resources in a device. For example, middleware may include at least one of a plurality of modules including an application manager, a window manager, a multimedia manager, a resource manager, a power manager, a database manager, a package manager, a connection manager, a notification manager, a location manager, a graphic manager, and a security manager. Furthermore, if a device has a phone call function, middleware may further include a phone call manager to manage a voice call function or a video call function. Middleware may further include runtime libraries or other library modules.

According to an exemplary embodiment, the first device 100 may receive a call request, e.g., an incoming call from the second device 200. In other words, a second user USER2 of the second device 200 may attempt to establish a phone call to a first user USER1 of the first device 100. Therefore, the first user USER1 may be referred to as a receiver, whereas the second user USER2 may be referred to as a caller or a sender.

A phone number of the second device 200 may be displayed on a display screen of the first device 100 (phone number 12, FIG. 1A), and the phone number 12 of the second device 200 may be referred to as a caller ID or a caller's number. If the phone number 12 of the second device 200 is included in contact information, e.g., a phone book stored in the first device 100, a name 11 of the second user USER2 stored in the contact information may be displayed on the display screen of the first device 100.

A phone number 14 of the first device 100 may be displayed on a display screen of the second device 200, and the phone number 14 of the first device 100 may be referred to as a receiver's number. Furthermore, if the phone number 14 of the first device 100 is included in contact information, e.g., a phone book stored in the second device 200, a name 13 of the first user USER1 stored in the contact information may be displayed on the display screen of the second device 200.

According to an exemplary embodiment, the first user USER1 of the first device 100 might not be able to respond to an incoming call from the second device 200. For example, the first user USER1 may be in a situation in which it is difficult to respond to the incoming call or the first user USER1 may not want to respond to the incoming call from the second user USER2.

According to an exemplary embodiment, when an incoming call is received from the second device 200, the first device 100 may automatically generate a response message (RM) by referring to information regarding an application that is being currently executed or previously executed and may automatically transmit the generated response message RM to the second device 200. To notify the first user USER1 that the response message RM is transmitted, the first device 100 may provide a notification that transmission of the response message RM is completed on the display screen of the first device 100 in the form of a message, for example. Here, the response message RM may include information regarding a current situation, a future situation, or both a current situation and a future situation of the first user USER1, or may be a simple response message.

According to another exemplary embodiment, when an incoming call is received from the second device 200, the first device 100 may provide a user interface (UI) element corresponding to the incoming call on the display screen of the first device 100. Here, the UI element may display options with respect to the received incoming call including allow, reject, or transmit a response message. If the first user USER1 selects to reject the incoming call or to transmit a response message, the first device 100 may automatically generate a response message RM by referring to information regarding an application that is being currently executed or previously executed and may automatically transmit the generated response message RM to the second device 200. Here, the response message RM may include information regarding a current situation, a future situation, or both a current situation and a future situation of the first user USER1, or may be a simple response message.

According to another exemplary embodiment, when an incoming call is received from the second device 200, the first device 100 may provide a user interface (UI) element corresponding to the incoming call on the display screen of the first device 100. Here, the UI element may display options with respect to the received incoming call including allow, reject, or transmit a response message. If the first user USER1 selects to reject the incoming call or to transmit a response message, the first device 100 may automatically generate response message candidates by referring to information regarding an application that is being currently executed or previously executed and provide the generated response message candidates on the display screen of the first device 100 together with general frequently used messages. As described above, the first device 100 may provide a response message list including response message candidates and general frequently used messages, the response message candidates may include information regarding a current situation, a future situation, or both a current situation and a future situation of the first user USER1, and the general frequently used messages may be simple response messages. Next, when the first user USER1 selects one response message in the response message list, the first device 100 may transmit a selected response message RM to the second device 200.

Here, the “current situation” may refer to a reason that the first user USER1 is unable to respond to an incoming call at a time point of reception of the incoming call, the reason determined by referring to information regarding an application that is being currently executed or previously executed and may be a specific activity, a location, or a route of the first user USER1. For example, if a navigation application is being executed on the first device 100, a current situation of the first user USER1 may be determined as ‘driving’ by referring to information regarding the navigation application (e.g., if the navigation application determines the phone is moving at or above a predetermined speed). For another example, if a fitness application is being executed on the first device 100, a current situation of the first user USER1 may be determined as ‘exercising’ by referring to information regarding the fitness application. As another example, if a phone application is being executed on the first device 100, a current situation of the first user USER1 may be determined as ‘on the phone’ by referring to information regarding the phone application.

The “future situation” may be a change of situation of the first user USER1 after termination of an incoming call, which may be estimated by referring to information regarding an application that is being currently executed or was previously executed and may correspond to an estimated point of time when the first user USER1 will be available to respond to an incoming call. For example, if a navigation application is being executed on the first device 100, a future situation of the first user USER1 may be estimated to ‘arrive at a destination in a few minutes’ based on information regarding the navigation application (e.g., a destination set by the first user USER1, current traffic conditions, etc.). As another example, if a fitness application is being executed on the first device 100, a future situation of the first user USER1 may be estimated to ‘finish exercise in a few minutes’ based on information regarding the fitness application (e.g., a target exercise time set by the first user USER1). As another example, if a phone application is being executed on the first device 100, a future situation of the first user USER1 may be estimated to ‘finish a phone call in a few minutes’ based on information regarding the phone application (e.g., an average call time of the first user USER1).

According to an exemplary embodiment, an application that is being currently executed or previously executed on the first device 100 may be executed by the first user USER1. In other words, functions of an application that is being currently executed or was previously executed on the first device 100 may be initiated based on a user input, such as a touch input from the first user USER1. The first user USER1 may intentionally execute an application installed on the first device 100 to perform a particular task. For example, the particular task may be driving, exercising, making or receiving phone calls, sending or receiving messages, inputting schedules, reserving movie tickets, reserving transportation tickets, watching movies, playing games, internet banking, etc. As described above, an application that is being currently executed or previously executed on the first device 100 are not limited to applications that are executed to determine a current situation of the first user USER1 or to estimate a future situation of the first user USER1 and may also be applications intentionally selected by the first user USER1 to perform particular tasks.

The first device 100 may generate a response message RM by using an application or middleware. Detailed descriptions thereof will be given below.

According to an exemplary embodiment, the first device 100 may generate a response message RM by using a phone application or a message application. In detail, a phone application or a message application installed on the first device 100 may receive information regarding another application via an API and generate a response message RM. Here, the response message RM generated by the phone application or the message application may be transmitted to the second device 200 via the message application.

According to another exemplary embodiment, the first device 100 may generate a response message RM by using a separate dedicated application. In detail, a separate dedicated application installed on the first device 100 may receive information regarding another application via an API and generate a response message RM. Here, the response message RM generated by the separate dedicated application may be transmitted to the second device 200 via a message application.

According to another exemplary embodiment, the first device 100 may generate a response message RM by using middleware. In detail, a particular module of middleware of the first device 100 may collect and manage information regarding various applications. Furthermore, a particular module of the middleware may generate a response message RM by using information regarding an application. Here, the response message RM generated by the particular module of the middleware may be transmitted to the second device 200 via a message application.

For example, methods of generating response messages RM via a phone application or a message application, a separate dedicated application, or middleware in a case in which a navigation application is being executed on the first device 100 at a point of time when an incoming call is received from the second device 200 will be described below in detail.

According to an exemplary embodiment, a phone application or a message application installed on the first device 100 may receive information regarding a navigation application via an API and generate a response message RM. In detail, the phone application or the message application determines a current situation of the first user USER1 as ‘driving’ based on information regarding execution of the navigation application and may estimate a future situation of the first user USER1 to ‘arrive at a destination in 30 minutes’ by referring to information regarding the destination and information regarding current traffic conditions from the navigation application. Therefore, the phone application or the message application may generate a response message RM saying “I am driving right now. I will contact you in 30 minutes.” The first device 100 may transmit the generated response message RM to the first device 100 via the message application.

According to another exemplary embodiment, a separate dedicated application installed on the first device 100 may receive information regarding a navigation application via an API and generate a response message RM. In detail, the separate dedicated application determines a current situation of the first user USER1 as ‘driving’ based on information regarding execution of the navigation application and may estimate a future situation of the first user USER1 to ‘arrive at a destination in 30 minutes’ by referring to information regarding the destination and information regarding current traffic conditions from the navigation application. Therefore, the separate dedicated application may generate a response message RM saying “I am driving right now. I will contact you in 30 minutes.” The first device 100 may transmit the generated response message RM to the first device 100 via a message application.

According to another exemplary embodiment, a particular module of middleware or an OS of the first device 100 may receive information regarding a navigation application via an API and generate a response message RM. In detail, the particular module of the middleware determines a current situation of the first user USER1 as ‘driving’ based on information regarding execution of the navigation application and may estimate a future situation of the first user USER1 to ‘arrive at a destination in 30 minutes’ by referring to information regarding the destination and information regarding current traffic conditions from the navigation application. Therefore, the particular module of the middleware may generate a response message RM saying “I am driving right now. I will contact you in 30 minutes.” The first device 100 may transmit the generated response message RM to the first device 100 via a message application.

FIG. 1B is a diagram illustrating a system that performs a function for providing a response message with respect to an incoming call, according to another exemplary embodiment.

Referring to FIG. 1B, a response message providing system may include first through third devices 100 through 300. Here, the first and second devices 100 and 200 may be substantially similar to the first and second devices 100 and 200 shown in FIG. 1A, and descriptions thereof given above with reference to FIG. 1A may be applied here.

The third device 300 may be a wearable device having communication function and data processing function, e.g., a watch-type device, an eyewear-type device, a hairband-type device, a ring-type device, etc. In detail, the first user USER1 may be wearing the third device 300, and the third device 300 may wirelessly communicate with and link to the first device 100

A user wears the third device 300, such that the third device 300 contacts the body of the user in a pre-set manner. For example, the third device 300 worn by the user may be in the form of a wristwatch, eyewear, an earring, a necklace, earphones, shoes, clothing, a helmet, etc.

According to an exemplary embodiment, the first user USER1 of the first and third devices 100 and 300 may not be able to respond to an incoming call from the second device 200. For example, the first user USER1 may be in a situation in which it is difficult to respond to the incoming call or the first user USER1 may not want to respond to the incoming call from the second user USER2.

According to an exemplary embodiment, the first device 100 may generate a response message RM by referring to an application that is being currently executed or previously executed on the first device 100 or an application that is being currently executed or previously executed on the third device 300. According to another exemplary embodiment, the third device 300 may generate a response message RM by referring to an application that is being currently executed or previously executed on the first device 100 or an application that is being currently executed or previously executed on the third device 300.

An exemplary embodiment in which operations for generating a response message RM and transmitting the response message RM are performed on the third device 300 will now be described.
